il. Claims. 1

The present invention pertains in general to organs of the type whereinthe note-producing apparatus is operatively connected to the keyboardthrough electric Wiring, and in particular to means for mounting thenote-producing apparatus in the organ cabinet.

Maintenance of organs frequently is a timeconsuming and inconvenientoperation due to the inaccessibility of many parts of the note-producing apparatus. Usually the apparatus for producing hundreds of notesmust be confined in a relatively small space, and this tends tocomplicate the work of repairing and adjusting the instrument.

An object of the present invention is to facilitate the maintenance oforgans by providing i1 proved means for mounting the note-pri apparatusin an organ cabinet whereby the apparatus may be wholly or partiallyremoved from the cabinet with very little effort.

A further object of the invention is to provide a mounting means of thetype described whicli is arranged to hold the note-producing apparatusin a position that facilitates maintenance thereof While it is partiallywithdrawn from the organ cabinet.

A further object of the invention is to provide a mounting means of thetype described which. may be swung into the cabinet when not in use soas not to detract from the appearance of the manner that it mayconveniently be withdrawn f Urlfrom the cabinet when desired, and beheld se curely in place at other times.

Still another object is to obviate or minimize the litter and disorderthat workmen ordinarily cannot avoid when servicing organs because .thesmall amount of space in which they can work effectively.

A further object is to provide means enabling the note-producingapparatus to be removed completely from the cabinet (without dismanmtling any portion thereof) for servicing it, oper ating it through anextension cable, or for re.n turning it to the factory for major repaircr replacement.

Various other objects, advantages and features of the invention will beapparent from the following specification when taken in connection withthe accompanying drawing wherein lected embodiment is set forth forpurposes ci illustration.

In the drawing, wherein like reference numerals refer to like partsthroughout:

Fig. 2 is a side elevational view 0f the mounting means as it appearswhen retracted;

Fig. 3 is a side elevational view, similar to Fig. 2, showing themounting means when extended;

Fig. fi is a plan view of the mounting means; and

Fig. 5 is a transverse sectional view of the mounting means taken alongthe line 5--5 of Fig. 2.

The organ indicated schematically in Fig. 1 is an airdriven reed type ofelectric organ in which the keys are mechanically coupled to a couplerboard i@ which is electrically connected by flexible cables i2 to theoperating magnets of various valve pallets disposed within a wind chestI4. rlhe pallets contro-l the flow of air from the wind chest to reedswhich are disposed within a reed frame it. The wind chest lt and reedframe I6 are carried bya supporting framework or housing ll for thenote-producing apparatus. An air compressor, for supplying air to thewind chest it, and an amplier, for amplifying the electrical signalsgenerated by the vibration of the reeds, are located in the lower partof the framework I'T.

The flexible cable l2 enables the whole noteproducing apparatus to beremoved from the organ cabinet it as a unit without interrupting any ofthe electrical connections necessary for operation thereof. Such remoteoperation of the noteproducing apparatus may be required if the com'-pressor noise proves objectionable, or where the weight of the consolemust be reduced to facilitate moving it about.

As the note-producing apparatus is quite heavy and bulky, it is verydesirable to mount it in such manner as to permit it to be either whollyor partially removed from the cabinet i8 with very little effort inorder to preclude any danger of injuring the mechanism. This featureenables minor repairs or adjustments to be made readily by a servicemanat the site of the organ and also facilitates return of the unit to thefactory for major repair or replacement.

In order to attain the foregoing object, the framework ll is provided ateach end thereof with fixed bars i9, horizontal when in normal position,each of which carries a pair of rotatably mounted 3 rollers which reston guide rails formed in mounting devices 22 which are secured tosidewalls 24 of the organ cabinet I8.

As may best be seen in Figs. 2 through 5, the mounting devices 22 areformed in two parts 26 and 28. The members 26 are secured to thesidewalls of the cabinet by screws 30. Each member 26 may be formed inone piece as a plate having a pair of spaced-apart parallel flanges 32and 36 extending normally therefrom. The lowermost flanges 32 formtracks, or guide rails, on which the rollers 2B rest. These flangespreferably are provided with longitudinally extending ribs 34 whichengage grooves in the rollers 20 to assist in guiding the rollers alongthe tracks when the framework I1 is withdrawn from or replaced in thecabinet. The uppermost fianges 36 serve as guard rails which cooperatewith the rollers 20 to prevent the frame I1 of the note-producingapparatus from being lifted completely away from the mounting devices 22so long as any of the rollers 2U is resting on its track 32.

The members 26 are provided at their rear ends with thick bifurcatedportions 31 having vertically extending slots 38 therein. The member 28of each mounting device 22 constitutes a rockable arm which is pivotedto the member 26 at the rear end 31 thereof, The arms 28 may each beformed as a substantially triangular plate having flanges 4U extendingfrom either side thereof along nearly the whole extent of the end leg ofthe triangle and thence across the top leg of the triangle adjacent theend portion 31 of member 26. The portions of the flanges 48 which extendalong said top leg of the triangular plate form r..

extensions of the track or guide rail 32 in the fixed member 26. Theportions of the flanges 40 which extend across said end leg of thetriangular plate form shoulders which abut against the bifurcated end 31of member 26 when each arm 28 is rotated to its fully extended positionas shown in Fig. 3. The triangular plate or web portion of the arm' 28extends beyond the flanges 40 to fit snugly in the slot or bifurcation38 in the end portion 31 of member 26. The arms '28 are pivoted on thefixed member 26 by means of pins 42 which are threaded or press-fittedin the end portions of the fixed members and pass through clearanceopenings in the arms 28. These arms 26 preferably are provided with ribs44, which extend lengthwise of the track portion of the arms inalignment with ribs 34 in members 26, to guide the rollers 20 during themovement thereof along such track portions.

When the note-producing apparatus is first installed in the organcabinet, the pivotal arms 28 are lowered to the position shown in Fig.3. The framework I1 is then raised over the arms 28 until the front setof rollers 2D rests on the arms 28 with the ribs 44 engaging the groovesin such rollers. The note-producing apparatus is then rolled along thetracks until the rear set of rollers 20 may be positioned on the arms28. At this time the framework I1 and the note-producing apparatus ofthe organ carried thereby will be supported in an inclined position, ashas been illustrated in Fig. 1. The slope of the track portions of arms28 maybe in the order of twenty degrees, but this may be altered asdesired. In this position, ready access may be had to the reeds housedin the reed frame I6 and to the pallet mechanism contained in the windchest I4. Also, sufficient clearance is provided to enable plug-inconnectors provided at either end of the flexible cable I2 to beattached to the coupler board I0 and to the wind chest I4. After thecable has been attached and all necessary adjustments have been made,the note-producing apparatus is pushed forward until both the front andrear rollers 20 rest on the flanges 32. The pivotal arms 28 may then beraised to the position indicated in Fig. 2. If desired, the arms 28 maybe locked in their raised positions as shown in Fig. 2 by suitable meanssuch as pins 46 to prevent the note-producing apparatus from movingabout in the cabinet during shipment thereof.

If at any future time it becomes necessary to work on the note-producingapparatus, the arms 23 are rotated to the position shown in Fig. 3 andthe framework I1 is withdrawn from the cabinet until the rear rollers 20reach the free ends of the arms 28. The track surface of these ends areturned upwardly to provide stops which prevent further movement of therollers 26 without lifting the note-producing apparatus from the arms28. The spacing of the rollers 2D preferably is such that only the rearpair of such rollers rests on the arms 28 when the framework I1 ispulled out, While the forward pair of rollers rests on the fixed members26 beneath the guard rails 36. The note-producing apparatus is supportedat a desired inclination from vertical whereby the upper end of theapparatus extends a substantial distance beyond the rear of the cabinetI9, thus affording access to the forward side of the wind chest I4.

From the foregoing it should be apparent that, by reason of the novelconstruction of the mounting means herein disclosed and described, anorgan has been provided wherein the note-producing apparatus may beconveniently withdrawn therefrom when it is desired to service the same.Furthermore, the mounting means permits a relatively cumbersomeapparatus to be partially withdrawn from the cabinet by one personwithout the exercise of any great effort and without endangering theapparatus. The mounting means also holds the partially withdrawnapparatus in such a position as to enable all parts thereof which mayrequire adjustment or replacement to be reached with ease.
